Denna jämförelsestudie ämnar att undersöka marknadens leverantörer av nätverksutrustning de- finierade som Software Defined Wide Area Networks(SD-WAN). SD-WAN är en innovativ teknik som applicerar virtualisering och Software defined networking koncept i Wide Area Networks (WAN) för att skapa kostnadseffektiva nätverk. Studien har utförts på företaget Curitiba som idag arbetar med konsulttjänster inom utvalda WAN-optimering och SD-WAN-produkter. Arbetets syfte är att utvärdera SD-WAN-lösningar och specificera i vilken typ av företagsnätverk lösningen bäst appliceras. Undersökningen börjar med en utredning av dagens organisationsnätverk för att kunna utföra en jämförelse mot SD-WAN. Därefter utvärderas fem leverantörer av nätverksutrustning definierade som SD-WAN, dessa är: Cisco IWAN, CloudGenix, Riverbed Steelconnect, Talari och Viptela. Produkter från Viptela utvärderas i ett test som undersöker komplexiteten i konfiguration av produkten. Utöver SD-WAN jämförelsen undersöks dagens state of practice och vilka fördelar samt nackdelar denna har över SD-WAN. Cisco IWAN är en sammanslagning av Ciscos tidigare funktioner som tillammans bildar en komplett SD-WAN-lösning, för att uppnå detta behöver produkterna kompletteras med programvarulicenser. CloudGenix är en nystartad nätverksleverantör som erbjuder en SD-WAN-produkt som liknar många andra aktörer men utmärker sig med avancerad applikationsidentifikation. Riverbed SteelConnect är intressant för organisationer som söker en simplifierad helhetslösning med ett centraliserat gränssnitt. Talari var en av de första SDWAN-leverantörerna och fokuserar på applikationsprestanda och pålitlighet men saknar några av funktionerna som de andra aktörerna erbjuder. Viptela erbjuder en simplifierad SD-WAN-lösning med hög skalbarhet. SD-WAN som teknik har många spännande funktioner, organisationer som planerar att investera i en uppgradering av WAN-infrastruktur bör undersöka SD-WAN alternativ. / Mälardalens Högskola Examensarbete Abstract This comparative study aims to investigate the markets vendors of networking equipment defined as Software Defined Wide Area Networks (SD-WAN). SD-WAN is an innovative technology that applies virtualization and software defined networking concepts in Wide Area Networks (WAN) to create cost-effective networks. The study has been done at Curitiba, a consulting firm in selected WAN-Optimization and SD-WAN products. The purpose is to evaluate SD-WAN solutions on today’s market and specify in what type of enterprise networks a solution should be applied. The investigation starts with examining todays enterprise networks to later compare them to SD-WAN. Five network vendors SD-WAN products will then be examined, these are Cisco IWAN, CloudGenix, Riverbed SteelConnect, Talari and Viptela. Products from Viptela is further examined in a test that investigates the complexity of configuring said product. Beyond the evaluation of SDWAN vendor’s, todays state of practice will be compared to SD-WAN. Cisco IWAN is a merge of Cisco’s previous features which together forms a complete SD-WAN solution, to achieve a complete solution the products must be complemented by software licenses. CloudGenix is a new networking vendor offering a SD-WAN solution similar to many other vendors but distinguish themselves with their advanced application identification. Riverbed SteelConnect is interesting for organizations looking for a complete and simplified solution with a centralized web interface. Talari was one of the first SD-WAN vendors and focuses on application performance and reliability but lacks some of the functionality other vendors offers. Viptela provides a simplified SD-WAN solution with high scalability. SD-WAN as a solution have many exiting features, organizations who plans to upgrade their current WAN-infrastructure should examine SD-WAN options

According to the combination of video/HDTV, data, and voice on a single medium, dubbed ¡§Triple Play¡¨, requires more sophisticated QoS (Quality of Service) features than are available in either VDSL1 or ADSL. Lastly, Triple Play services, with a minimum of three TV channels, several VoIP connections, and sufficient speed for Internet access, require high data rates of at least 30 ¡V 40 Mbit/s, about twice of what can be achieved under real field conditions with today¡¦s ADSL2+ solutions. VDSL2 was developed and standardized in record time to address the shortcomings of existing access technologies. It serves as the ideal xDSL technology for eliminating last-mile bottlenecks and to enable global mass deployment of advanced Triple Play services.
